Hi,
We installed OBSD's ssh package on production and find our batch jobs
are hanging on the "ssh"
command. The details are included below, for both normal and
"hanging"
executions. Please let
me know if this is a new or existing bug or if you require further info
to debug this. The command
was executed with the highest debug level (-v -v -v for level 3). This
script
serves a critical business function and this bug affects our database
recoverability.
Thanks,
